JC, I have so many wires behind my computer, plus the router, power box, high speed connection, speaker woofer, printer connections, I am sure it is a "dust bunny heaven"! ROF!!
It is, yorkie, because when B. was working on my computer, we had to get back in there some and you should have seen it. I got the little vacuum and got as much as I could. Too many cords and wires that you can hardly clean.
